Yeah.....They
could be....but would they?
Considering they're roughly a story shorter than Godzilla, maybe more, One would think Big G would have a slight advantage against them.
Then again, Ultraman'll always be faster than him, regardless of how tall Godzilla is. So speed is key.
I think one on one, they'd have a pretty decent fight 'til dawn or 'til Godzilla takes Ultra down to the ocean depths with him.
However, knowing Ultraman, he'll call his homeultras for a dignified fly-by on Godzilla...then a gang beatdown.
Rich, ain't it?
